What is the concept of java escape characters and how to use them

1. Concept

There are some characters in java that have special functions. If you want to express the character itself without expressing special effects, you can use escape characters at this time. .

2. Use

escape characters starting with \

\t Tab character: One tab character position represents 8 spaces

If the previous content satisfies an integer multiple of the tab position, re-open a tab position with 8 spaces

If the previous content is not satisfied, not a whole tab position

\n Line break

\b Cursor backspace

\r Cursor returns to the beginning of the line

3, Example

/* java中的转义字符 */ public static CharTest02{ public static void main(String[] args){ char c1 = 't'; System.out.println(c1); //根据已学内容，以下代码应该报错： //经过测试，以下代码可以通过编译，所以一下代码“\t” //实际上是一个字符，不属于字符串 //两个字符合在一起表示一个字符，其中\t边上“制表符tab” char c2 = '\t'; System.out.println("abc\tdef"); System.out.println("HelloWorld"); System.out.print("HelloWorld"); //"\"的出现会将紧挨着后面的字符进行转义 } }
